[QUOTE= I was briefly looking at some numbers as far as flow and pressure and to use golf course heads like the hunter valve in heads we need 100 psi and roughly 80 gpm which means 3" main, which probably means gasketed pipe.

No, a gasket type pipe is not necessary for the limited flow and pressure you are quoting. Also, dependent upon the environmental/site conditions, flow rate per zone may end up with differing requirements. Things like turf type, slope, elevation above irrigation point source, degree/duration of sunlight/shade, usage of site - all go into properly designing the system.

So now i am thinking I40's with opposing nozzles. But I know there are issues that arise with reclaimed water where water treatment to prevent lawn diseases can arise.[/QUOTE]

The "issue" as you identify it deals more with the type of pipe/valve/irrigation head component selection than actual concern over reclaimed water use and C3 turf irrigation requirements.

Unless you have some really weird elevation concerns, this sounds like an "off the shelf" component system.

I used 10,000 gallons per acre, because we use 27,000 gallons per acre-inch, so watering an acre three times weekly to the nominal standard of an inch of watering gets you to a 10,000 gal tank to even supply one cycle of watering on an acre. Multiply by the number of acres, times the number of weeks worth of water you are trying to store, and you got one bigass storage tank.

T'was what i was getting at.

The OP hasn't seen prints nor the site and has no idea of the scope of work to be done, just what hes been told.

Once he sees the prints he'll know more and share the specs with us i hope.Posted via Mobile Device

Why the screwin around with storage tanks if you can draw direct off the lake? 80gpm on golf heads is nothing, the heads im used to blow through 45gpm each... im thinking you should go with an on-demand pump on a vfd.
